It would be highly interesting to read the contract which is ready already, just waititng for Marcus' signature. Like jonkka said, all the travel days away from home, PR which he has never been too keen of, and now lately the amount of testing, they're all bugging him. That was indeed in the interview he gave.
How much do you think Malcom Wilson is willing to come forward, just keep him driving next year? I mean, in terms of all those responsibilities?
Also, one year contract, one year of driving = might be a helluva amount of money. Might be a motivator.
